FROM THIS EPISODE

Since President Obama got rock-star treatment five years ago and was awarded the Nobel Prize, US relations with Europe have declined, instead of improving. The economic downturn, NSA spying and the pivot toward Asia have not helped. Now, Russia's threat to Ukraine gives new importance to economic ties to the European Union and the to the role of NATO. We update this week's presidential visit. Also, Osama Bin Laden's son-in-law is convicted of conspiring to kill Americans, and Facebook invests big money in virtual reality.

Today, Barack Obama made his first visit as President to Brussels, headquarters of both the European Union and the NATO alliance. In a speech to 2000 young people, he delivered his harshest words yet for Russia’s Vladimir Putin, calling him a "menace" to the international system built by the United States and Europe since World War II. He said, if Putin thought he could drive a wedge between the US and Europe, he "clearly miscalculated," and warned that Russia’s "isolation will deepen." We hear about his first visit as President to the headquarters of the European Alliance and NATO. Is he right that Russia is only a "regional power?" Who's showing the most strength — or weakness, the President or Vladimir Putin?

For the first time, an accused terrorist charged with involvement in the attacks of September 11 has been convicted in US civilian court. Today, a jury in New York City — just blocks from the former World Trade Center — pronounced Sulaiman abu Ghaith guilty of conspiracy to kill Americans, providing material support to terrorists and conspiring to do so. Tina Susman has covered the three-week trial for the Los Angeles Times.
